Ellie

Ellie is an artificial intelligence-powered email writing assistant and browser extension designed to help busy professionals, founders, sales representatives, and customer support specialists conquer their inboxes in a fraction of the usual time. Built to act as a digital executive assistant, the software learns individual writing styles to compose thoughtful, contextually appropriate email replies.

The platform integrates seamlessly into major web email clients including Gmail and Fastmail, as well as Microsoft Outlook via dedicated browser extensions. When reading an incoming email thread, users click Ellie to summarize the key points, choose an intended response tone—such as respectful, casual, interested, or declining—and generate an articulate response that matches the user's authentic voice. Ellie can also pull facts from uploaded documents to answer company-specific inquiries accurately.

Ellie operates via browser extensions for Google Chrome and Mozilla Firefox, backed by a secure cloud backend that encrypts email data in transit. The service provides a generous free plan that allows users to generate introductory email replies daily, alongside tiered monthly and annual subscriptions that unlock unlimited replies, advanced tone customization, and custom knowledge base integrations.
